para_hpt37x: bus clock 33MHz, using 50MHz DPLL.
ACPI: PCI Interrupt 0000:00:0d.0[A] -> GSI 16 (level, low) -> IRQ 17
scsi2: pata_hpt37x
scsi3: pata_hpt37x
ata3: PATA max UDMA/100 cmd 0x0001efa0 ctl 0x0001ef9e bmdma 0x0001ec00 irq 17
ata4: PATA max UDMA/100 cmd 0x0001ef90 ctl 0x0001ef9a bmdma 0x0001ec00 irq 17
